[ 1/1Inequality]
Assignment:Find the solution set of inequality x∧3/(2x∧2-x-6) ≥0 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
x ^ 3 / ( 2 * x ^ 2 - x - 6 ) ≥0 (1)
From the definition field of divisor
2 * x ^ 2 - x - 6 ≠ 0 (2 )
From inequality(1):
-1.5 ≤ x ≤ 0 或 x ≥ 2
From inequality(2):
x < -3/2 或 -3/2 < x < 2 或 x > 2
From inequalities (1) and (2)
-3/2 < x ≤ 0 或 x > 2 (3)
The final solution set is :
-3/2 < x ≤ 0 或 x > 2Your problem has not been solved here? Please take a look at the hot problems !
